The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.
Outlines the election of J. D. Forbes and attributes his success to JH's letter. Regarding the work of Thomas Henderson. Pity JH has to waste time doing his own reductions. Paris observations. Saw the comet in Valparaiso. Magnitude of stars compared to the moon. Hopes he liked his own recent book. Pleased the sextant is of use.
Sends a small dispatch from J. D. Forbes. The barometer seems to have no connection with the weather this winter. Had a snow shower but could see no clouds in the sky. Preparing for the occultation of Mars.
Encloses a dispatch from Thomas Henderson, who is very pleased with his work and a word from JH would spur him on. Is more out of touch with science at Edinburgh than JH is at the Cape. Young engineer, J. S. Russell, has idea for swift towing canal boats. Doubtless he has seen Francis Baily's supplement on John Flamsteed.
Further information about boats in canals. Sends proof sheets of the article in question.
Is pleased to hear the Herschels are contemplating their return but regrets it will not be via Rio. J. D. Forbes is progressing well, may be in danger of overwork. Thomas Henderson too is doing good work at the Observatory. Gives results of lunar eclipses of Oct. 1837.
P.S. Has received her letter regarding travel home via Rio and will endeavor to find out the answers and send letters of recommendation later; is now in Paris. Hopes to send a copy of a small book he has written. Hoped to include something from D. F. J. Arago but it has not arrived yet. The French are unpunctual.
Provides an account of JH's observatory arrangements, some interesting observations, and the effect of the weather on observing.
